I received my first Rubik’s Cube in 1980, when they arrived in SA for the first time. I got a manual with it. See cover pic below. This manual was printed in South Africa and also in my home language (Afrikaans)
Combining the standars algorithms and algorithms from this manual, I have the easiest way to solve the standard 3×3 cube, the same moves can be used to complete the Megaminx, without learning additional algorithms. See my page My Solver.
